In an extraordinary comeback, a Queensland family have won a prestigious national award just five years after their prawn farming operation was wiped out by disease.
In 2016 the Zipf family's $1.5 million dollar prawn crop was destroyed and its hatchery, which supplied other growers, was closed after the discovery of the highly infectious and deadly-to-prawns white spot disease.
They took a huge gamble by re-purposing empty prawn ponds and equipment to farm two fish species new to Australian aquaculture.
